The City of Lake Oswego is holding an industry forum tomorrow to discuss plans to procure a wastewater treatment plant project as a public-private partnership (P3). 

The authority intends to develop a new wastewater treatment facility in the city, located in Clackamas County, Oregon, north-west USA, using a design, build, finance, operate and maintain (DBFOM) contract with private partners.

The project was first proposed by national real estate development company SunCal in November 2017 to replace the existing Tryon Creek wastewater treatment plant. The company's design fully encloses the treatment plant area, reduces the facility’s overall (upgraded) footprint from 15 acres to approximately 3.5 acres and results in higher water quality that is discharged into the Willamette River.

Constructed in 1964, the Tryon Creek plant is aging and must be upgraded over time to meet increasingly stricter treatment standards and improve efficiencies. US$133 million worth of improvements have been identified over a 30-year timeframe.
